Endovascular intervention is expected to become increasingly popular in medical practice, both for diagnosis
and for surgery. Accordingly, researches of robotic systems for endovascular surgery assistant have been carried out
widely. Robotic catheter navigation systems are with advantages of higher precision, can be controlled remotely etc.
However, the haptic feelings, the important function for propelling robotic catheter navigation system sre immature. In the
paper, a robotic catheter navigation system is proposed. The navigation system is designed to simulate the surgeon’s operating
procedure. And the haptic feedback issue is concerned. A clamping force measurring method is developed. Therefore,
surgeons can carry out operation with their own skills. System implement and performance are presented.
